But why ?: Why would you be concerned about such a thing? Use a dab of toothpaste and spit it out when you are finished brushing your teeth. Do not eat the toothpaste.

Compulsion: You keep asking the same question over and over, always getting the same answer. You're going to get full before you ever consume enough t'paste to be harmful. Follow package directions. Do not, as you have done in the past, deliberately eat t'paste. See a mental health professional about your anxiety/compulsion problems. See your Dentist/Hygienist about appropriate Oral Hygiene.
